Application sied February 7, 190s. serial No. 414,779.

To all wiom it may concern:

Be it known that I, ALvA WATTS, a citizen of the United States, residing at New Brighton, in the county of Beaver and State of Pennsylvania, have invented new and useful Improvements in 'Bottle-Making Machines, of which the following is a specification.

This invention relates to bottle making machines and more particularly to a machine for dressing or grinding the tops of the bottle necks.

The invention has for one of its obiects to improve and simplify the construction and operation of machines of this character so as to be comparatively simple and inexpensive to construct and keep in repair, thoroughly reliable and eflicient in use, and whereby a large number of bottles can be ground in one operation.-

A further object of the invention is to provide a machine by which a large number of bottles can be ground at one time and with comparatively little expense and cwhich is provided with bottle holders which can be quickly and easily taken out when the bottles are finished and replaced after they have been ie-charged.

Another object of the invention is to provide a head having provision for receiving a plurality of holders, said head being arranged on va suitably driven shaft disposed in operative relation to the grinding wheel or stone.

A still further object of the invention is the employment of a simple form of means for clutching and unclutcliing the head cariU ing shaft with respect to the power shaft so that the former can be held stationary while taking out and putting in the bottle holders.

With these objects in view and others, as will appear as the desciiption proceeds, the invention comprises the various novel features of construction and arrangement of vparts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

, In the accompanying drawing, which illustratesone of the embodiments of the invention, Figure. 1 is a front view of tl le machine. Fig. 2 is a plan view. of a bottlo-carrying head drawn on an enlarged scale. Fig. 3 is a central vertical section of the head. Fig 4 is a transverse section on line 4 4, Fig. 3.

Fig. 5 is a perspective view of one section of a bottle holder.

Similar' reference characters are employed.

to designate similar parts throughout the several figures of the drawings.

Referring to the drawing, A designates a supportingframe of any suitable construction and comprising in the present instance uprights 1, a top crosspiece 2, intermediate cross-pieces 3, and a table 4. Mounted above the table is a basin 5 in which rotates the grinding wheel or stone 6. The stone 6 is keyed to a vertical driving shaft 7 having its lower end mounted in a step bearing 8 in any approved manner and steadied in its upper end in a bearing box 9 on the top crosspiece 2. On the upper portion of the shaft 7 is a ulley 10 for receiving a belt whereby the mac ine is driven.

'iJisposed parallel with the driving shaft 7 are a plurality of head carrying shafts 11 mounted in .bearings 12 on the intermediate cross-pieces 3. -Iii the present instance two of such shafts are shown, but it isto be understood that any desired number may be employed. are friction wi."els 13 that peripherally engage with a small friction wheel 14 on the driving shaft 7, whereby the head carrying shafts 11 are frictionally driven at a somewhat slower speed than the stone driving shaft 7. In order to hold the shafts 11 in :inoperative position when the bottle holders are to be removed, each shaft is provided with a level' carrying a counterb-.ilance weight. Disposed inwardly from the uprights 1 and secured to the cross-pieces 3 are posts or standards 1501i each of which is a lever 16 fulcrumed at 17 and having-at its outerend a weight 18. The inner end of the lever is bifurcated or otherwise formed to engage around the adjacent ,head carrying shaft 11, as indicated by 19. On the shafts 11 are ixed collars 20 under which the bifurcated ends 19 of the levers engage. The shafts 11 are clutched to the friction wheels 13 so that.the former can be idle during the taking out and placing of the 'bottleholders in the lieads on the shafts 11. These clutches may' be of any approved construetion and iii the present instance, each coniprises a disk 21 keyed to its respective shaft 11 and provided with a diametrically extending rib 22 on its under surface adapted to engage in a diametrical slot in the upper end of the hub 23 of the adjacent friction wheel 13. Thus, upon raising the shafts 11 and by pulling down on the outer ends of the levers, the

On the upper ends of the shafts 11 ers can bc taken out and ins irte l Vsections 31 and 32 in' which are formed cells ribs '21 are disengaged lroin the clutch ineinbers lon the wheels 13, whereby the wheels rotate idly. The levers can be held in d-epressed position for holdingthe shal'ts out of connection with the wheels 13 in any suitable manner, as for instance by buttons lo' on the uprights l, so that the bottle holders can he conveniently talrcn out of and placed in the heads l. ln order to prevent the bottles from being ground beyond a certain extent, stops in the form of adjustable colla-rs 24 are secured to the shafts 1 l. to engage with the lower bearings 12 for the latter when the bottles have been ground to the liniit. Vfhen the stops thus bear on the bearings 12, the machine can continue to operate indelinitely without grinding the bottles, this heng an important feature, since the constant care of the operator is unnecessary so that ie can be engaged in other worl: such as vlillinrr holders to get them ready for another charg ing of heads..

The holders on the shafts l l each comprise a suitably shaped hody dos rated generally by B. This body, in the present instance, le east crucilorin with its arms hollow l'roni their outer extremities to the contrai portion or hub 26. I By having the arias op n at i their outer ends, the individual hottie holdin a siz'uple "5 are open at and easy manner. The arms the bottoni and are provided with plate that are secured in place hy bolts 2r; pas. i through the platos and hoi-ed bosses 29 on the sides of the arms, the said 1oolts being' pro vided with wing nuts 230, Fthe pl 2? are each rovided with centrally dispos ad longitudinal slot 3G through which the necks ol the bottles protrude, so es to be operated on by the J;ri nf.lin ry wheel 6. The shafts il l re secured in the hubs 26 in any suitable inanner. Each bottle holder is composed ol two or chambers 33, those of one section registeringr with the cells or chambers ol' the other section so as to receive the hotties tofljie ground. Each holder is preferably in the form of a parallrlcpiped and is adapte-dto slide into its roepen-tive arm 25 of' the ,read i3 inwardly and outwardly through the open endthereof and the bottoni of the holder rests on the plateI 27 of tl'iesaid arm. A top clamping plate Sil is arranged in each arm tobear on thc top of the bottle holder'and this plate is clamped in position hy a screw 35 passing upwardly through the armvand fitted with a hand Wheel 3th To clamp-the two sections of the bottle together while the latter is in position on the head, a side clamping plate 37 is employed to bcar against the section 32 as shown in Fig'. Ll, and this clamping late is provided with a screw 38 having rand v. "reel 39.

From the foregoing description, taken in connection with the accompanying drawing,

` 'll may be uuclutrhcr the advantages olt the consrruction and ol" the. method oll operation will bc readily apparent to those skilled iu the art to whichthoinven- 'tion apperlaius. ln operation, the bottles to bc ground are a rranged in the holders and the latter are slid radially into tho sovcral'arins or chambers in tho heads i'l, tho latter boing' stalionarv by reason ol' thc hmfdwarryinir shafts l] hein.; uuclutched troni the friction wher-ls l.
